My previous fresh-air duct has seen better days, so I snagged this updated version (no accordion or front mounting tab) on a recent JY run, and cleaned it up. I also used a heat gun to open both ends fully, and then washed it inside & out. I've had a big roll of foil-faced bubble wrap for a few years, and I was able to cut this piece from the scrap left over from the evaporator cover. A few coats of adhesive, and it looks like it belongs there.
One of these days, I'll redo the filter cover & clean-air tubes.
